The Tank Hollow Fire remains at more than 5,000 acres with 40% containment.

Over the past week, fire behavior has been favorable for beneficial, low-intensity fire spread. Downed, dead trees and undergrowth has been consumed while healthy, live trees are preserved.

Fire managers took advantage of favorable conditions to widen the vegetation gap by burning along several roads northeast of the fire area. These lines will be used to confine the fire as it continues to advance northward.

As near record high temperatures and very low relative humidity develops, fire behavior is expected to increase significantly. Fire is likely to reach the forest canopy over the next several days.

Smoke from the Tank Hollow Fire has been rising and moving out laterally, but large volumes of smoke from numerous larger fires in the Pacific Northwest and Montana is causing hazy conditions along the Wasatch Front. Incident meteorologist, Dan Borsum, reported that the national smoke impacts to Utah will get worse before they get better.
